Ensemble-Based Confidence Scores

Your weather app just told you there's a 80% chance of rain.

But how much can you trust that number?

We run up to 133 weather simulations per forecast and show you the confidence behind every prediction. Know when to plan confidently—and when to stay flexible.

The Problem with Weather Forecasts

Every weather API gives you a number. What they don't tell you is how much that number is worth. We do.

01

When 100+ Models Agree, You Can Plan

133 weather simulations per forecast. When they converge, you know it's solid. When they scatter, stay flexible.

02

Stop Planning Around 'Maybe'

"30% chance of rain" tells you nothing. We show the full distribution—drizzle vs. downpour—so you know what you're dealing with.

03

Confidence Scores You Can Bet On

95% confidence? Lock it in. 40%? Have a backup plan. No more guessing how much to trust the forecast.

04

Decisions That Don't Haunt You

Cancelled an event for clear skies? Sprayed crops before rain? We help you make the call with eyes wide open.
